Drop-in replacement for the V2_Trident_Front_Cover of the BFI (Beefy Front Idler) V2.4, with an integrated mount for a MakerBeam XL 15×15 extrusion that carries the Bondtech INDX tool docks.
What this is
The Bondtech INDX toolchanger parks its tools on passive docks ( INDX Tool Dock 1515 Makerbeam , 02PRT00392) that clamp onto a 15×15 extrusion. On a Voron 2.4 there is no obvious place to put that bar. This part solves it: it replaces both front covers of the BFI V2.4 front idlers and adds a cradle holding the bar across the front of the gantry, at exactly the height the INDX toolhead expects. Nothing else is modified. The bar rides on the gantry, so tools stay fixed relative to the toolhead.
Left and right are not mirror images. The A/B belts run on different planes, so the left idler sits 10 mm lower — each side compensates internally.
Geometry (verified against CAD)
Description | Measures |
|---|---|
Bar axis | 6.40 mm above the MGN12 X-rail axis |
Bar Top face | 3.80 mm above the gantry 2020 extrusions |
Toolhead reach at tool change | +7.1 mm margin |
Bar length — Voron 350 / 300 / 250 | 428 / 378 / 328 mm |
Derived from Bondtech's INDX_simplified_1.17.step , cross-checked against a full Voron_2.4r2_Assembly.step . Room for 6 docks (161.4 mm).
Requirements
1. BFI V2.4 front idlers — replaces their covers; won't work with stock idlers.
2. DraftShift DoorBuffer (or no front doors). Not optional
3. MakerBeam XL 15×15
Hardware
• 2× M5×30 BHCS per side — the original screws, unchanged length
• 2× M3×8 BHCS per side for clamping
• 1× MakerBeam XL 15×15, cut to length
Printing
Flat on the screw-hole face (as oriented in the STL).
Status
First test release — not yet printed or fitted on a real machine. All of the above is derived from CAD. The tightest number is the +7.1 mm Y reach margin. Feedback welcome.
